Description

Technical Field

[0001] The utility model relates to the field of security, in particular to a door lock component and a special rolling door lock for a silver pavilion. Background Art

[0002] Rolling shutter doors are made of multi-jointed door panels connected in series. The doors rotate up and down around the scroll above the door in a fixed slide. Rolling shutter doors are commonly used in shops, supermarkets, shopping malls, banks and other occasions.

[0003] Among them, the door locks of conventional rolling shutter doors are all arranged on the door body of the rolling shutter door, and the lock hook holes are arranged on both sides of the door column. When the rolling shutter door is closed, the door lock of the rolling shutter door extends out and is inserted into the lock hook hole to achieve the locking of the rolling shutter door. Among them, for ordinary mechanical door locks, it is necessary to manually unlock or lock with a key, and its locking and unlocking are not convenient or fast enough. For electric door locks, electric drive is used to achieve locking or unlocking. Among them, due to the existence of the electric door lock motor, it will occupy a large thickness space, and it is arranged on the door body, so that the door body will protrude at the position of the door lock, which is not beautiful, and the door lock is easy to be located and easily destroyed in a targeted manner. At the same time, for the rolling shutter door dedicated to the silver pavilion, due to the high protection requirements, the lock head of the electric door lock is generally a single-point lock with limit, or a two-side limit, and the lock plate is extended to hook in the lock hole. In this way, it is easy to be damaged when subjected to external force. If the lock plate is thickened to increase the strength, its weight will be relatively large, and the size of the motor of the electric door lock will increase, which will further lead to unsightly appearance and easy damage. If an ordinary mechanical door lock is used, manual locking is required, and the locking speed is slow.

[0044] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0045] Example 1: See Figure 1-7 As shown, a door lock assembly includes a door lock mounting frame 71, a door lock portion 72 mounted on the door lock mounting frame 71, and a slide plate 73.

[0046] The door lock part 72 includes a lock pin 721 and two lock tongues 722. The lock pin 721 is mounted on the door lock mounting frame 71. The middle parts of the two lock tongues 722 are rotatably connected to the lock pin 721.

[0047] A locking hook 7221 bent inward is disposed above each locking tongue 722, and a locking hook groove 7222 is formed below the locking hook 722. The locking hook 7221 is disposed above the locking pin 721, and the locking hooks 7221 of the two locking tongues 722 are disposed opposite to each other, and the two locking hook grooves 7222 form a locking groove 7223; the locking tongue 722 below the locking pin 721 forms a locking tongue pushing portion 7224;

[0048] The slide plate 73 is slidably disposed on the door lock mounting frame 71 below the lock pin 721. A lock tongue switch slot 731 is disposed in the middle of the slide plate 73. The lock tongue pushers 7224 of the two lock tongues 722 are respectively disposed in the lock tongue switch slots 731.

[0049] When the slide plate 73 slides horizontally, the lock tongue switch groove 731 pushes the two lock tongue pushing parts 7224 to move closer to each other or away from each other, so that the top of the lock groove 7222 is opened or closed.

[0050] In this embodiment, the rolling shutter door will be located above the door lock assembly, and the bottom of the rolling shutter door will have a lock accessory that can be limited by the lock groove, such as round steel, square steel or other structures. Among them, taking the initial state that the top of the lock groove is open as an example, after the rolling shutter door is lowered, that is, after the rolling shutter door is closed, the lock accessory at the bottom of the rolling shutter door will enter the lock groove from between the two lock hooks. At this time, since the lock groove is in an open state (the tops of the two lock hook grooves are away from each other, so that the top of the lock groove is open), the rolling shutter door can be opened (that is, the lock accessory can rise and leave the lock groove). When the rolling shutter door needs to be locked, the slide plate moves. When the slide plate moves, it will also drive the lock tongue switch groove to move. The movement of the lock tongue switch groove drives each lock tongue pushing portion to rotate relative to the lock pin. When the lock tongue rotates around the lock pin, the lock hooks of the two lock tongues are close to each other, thereby closing the lock groove. At this time, the lock hook will be above the lock accessory. In this way, when the rolling shutter door wants to be opened, the upward movement of the lock accessory will be limited by the lock groove (lock hook), thereby achieving the locking of the rolling shutter door. When the rolling door needs to be opened, the rolling door is unlocked first. When unlocking, the slide moves in the opposite direction, and pushes the lock tongue push part to rotate in the opposite direction around the lock pin through the lock tongue switch groove, so that the lock hooks of the two lock tongues move away from each other and the lock groove is opened. At this time, the lock accessory of the rolling door can move upward and disengage from the lock groove, thereby realizing the unlocking of the rolling door, and the rolling door can be opened smoothly.

[0051] In the present invention, the door lock assembly can be directly arranged directly below the rolling door. For example, a groove is pre-drilled in the ground, and the door lock assembly is installed in the groove to prevent it from leaking out. If the rolling door is subsequently destroyed by external force, since the rolling door has been closed and its bottom is inserted into the groove in the ground, the door lock (or keyhole) cannot be found, and it is impossible to unlock it by external force. The rolling door itself can only be destroyed. In this way, for the rolling door dedicated to the silver kiosk, due to the particularity of the silver kiosk, the strength of the rolling door will be very high. The rolling door can withstand external force destruction of a certain time and intensity, and sufficient reaction time is given to deal with this problem. Therefore, the use of the door lock assembly in the present invention can effectively improve the safety of use.

[0052] See also Figure 3 , 7 As shown, there are two lock tongue switch slots 731, and the two lock tongue switch slots 731 are arranged opposite to each other. In this embodiment, the two lock tongue switch slots are symmetrically arranged. The two ends of the lock tongue switch slot 731 are respectively a first end 732 and a second end 733, the first end 732 is arranged close to the central axis of the slide plate 73, and the second end 733 is arranged away from the central axis of the slide plate 73;

[0053] The first ends 732 of the two locking tongue switch slots 731 are arranged close to each other, and the second ends 733 of the two locking tongue switch slots 731 are arranged far away from each other.

[0054] In this embodiment, taking the direction shown in the figure as an example, the first end is close to the right side of the slide plate, and the second end is close to the left side of the slide plate. The lock tongue switch groove can be an oblique groove, which is arranged outward from the first end to the second end from right to left, or the lock tongue switch groove between the first end and the second end has an oblique groove and a transverse groove that are interconnected, or other combinations. As long as the second end is outside the left side of the first end, in this embodiment, the lock tongue pushers of the two lock tongues are respectively in the positional relationship of the front and rear sides, so the two lock tongue switch grooves are also arranged front and back, and the second end of the lock tongue switch groove on the rear side is at the left rear end of the first end, and the second end of the lock tongue switch groove on the front side is at the left front end of the first end. In the process of the slide plate moving to the left, since the two first ends are close to each other, the two lock tongue pushers will be pushed to approach each other through the limit of the lock tongue switch groove. Since the lock tongue and the lock pin are rotatably connected, in this process, the lock hooks of the two lock tongues will be pushed away from each other, so that the lock groove is gradually opened. In the process of the slide plate moving to the right, since the two second ends are gradually away from each other, the two lock hooks are close to each other, and the lock groove is closed.

[0055] For further information, see Figure 7 As shown, in order to facilitate the processing of the lock tongue switch groove, the middle parts of the two lock tongue switch grooves 731 are connected through a middle connecting groove 734, the right end of the middle connecting groove 734 is arranged close to the first end 732, the left end of the middle connecting groove 734 is arranged between the two second ends 733, and there is a horizontal spacing between the left end of the middle connecting groove 734 and the left end of the second end 733;

[0056] A V-shaped separation portion 735 is also provided at the left end of the middle connecting groove 734, and the tip of the right end of the V-shaped separation portion 735 is arranged opposite to the middle between the two first ends 732, and the two side walls of the V-shaped separation portion 735 are respectively connected to the inner side surfaces of the two second ends 733.

[0057] In this embodiment, by setting the middle connecting groove, the two lock tongue switch grooves form a whole, which is convenient for rapid processing of the lock tongue switch groove (for example, when using a whole steel plate to mill the lock tongue switch groove, after pre-opening the hole, the milling cutter is introduced into the hole position, and the milling is directly performed along the edge of the lock tongue switch groove to mill off the excess steel plate in the lock tongue switch groove, without the need to withdraw the tool and re-position it, and the same reference can be used for rapid processing, with high processing efficiency, higher precision and better quality). At the same time, since the middle parts of the two lock tongue switch grooves are connected through the middle connecting groove, in order to ensure that when the slide plate moves to the right, the two lock tongue pushers can respectively enter the two second ends, therefore, by setting the V-shaped separation part, when the slide plate moves to the right, the two first ends respectively move to the right and disengage from the corresponding lock tongue pushers. The movable part, at this time, since the outer side walls of the corresponding lock tongue switch grooves are far away from each other (the distance between the outer walls of the two lock tongue switch grooves will be greater than the sum of the widths of the two lock tongue pushing parts close to each other), therefore, in this process, the two lock tongue pushing parts will not rotate relative to the lock pin. In order to ensure that when the slide plate moves to the right, the two lock tongue pushing parts will not be blocked or collided by the left side wall of the middle connecting groove, resulting in the corresponding lock tongue pushing parts being unable to smoothly enter the corresponding second end, therefore, through the setting of the V-shaped separating part, the V-shaped tip of the V-shaped separating part is set opposite to the middle between the two first ends, that is, opposite to the gap between the two lock tongue pushing parts. When the slide plate moves to the right, the two lock tongue pushing parts will be separated and guided by the V-shaped separating part, so that the two lock tongue pushing parts respectively enter the corresponding second ends, thereby realizing the closing of the lock groove.

[0058] Each of the lock tongue pushers 7224 is inserted into one of the lock tongue switch slots 731. When the lock tongue pushers 7224 abut against the first end 732, the two lock hooks 7221 move away from each other, so that the top of the lock slot 7223 is opened.

[0059] When the locking tongue pushing portion 7224 abuts against the second end 733 , the two locking hooks 7221 approach each other, so that the top of the locking slot 7223 is closed.

[0060] See also Figure 4-6 As shown, the top surface of each locking hook 7221 is an inclined surface 7225 , and the inclined surface 7225 is arranged to be inclined inward from top to bottom, and the locking hook groove 7222 is arranged directly below the inclined surface 7225 .

[0061] In this embodiment, when the locking accessory at the bottom of the rolling door moves downward, that is, when the rolling door is closed, even if the distance between the two locking hooks is not greater than the width of the locking accessory, due to the presence of the inclined surfaces, the two inclined surfaces form an upward-opening V-shaped structure or an inverted eight-shaped structure. At the same time, due to the deadweight of the rolling door, the locking accessory will push the locking hooks to rotate outward, and the resulting lock groove will open, and its width can ensure that the locking accessory can smoothly enter the lock groove.

[0062] Preferably, the bottom surface of the lock hook is a hook surface, and the hook surface is a structure that is inclined upward from the inside to the outside or is an upward convex arc structure, so that when the lock hook is close and the lock slot is closed, the hook surface of the lock hook hooks on the top of the lock attachment to limit it. In the closed lock slot, even if the rolling door wants to be opened, when the lock attachment at the bottom is subjected to an upward pulling force, the hook surface will hook the lock attachment and prevent it from being opened.

[0063] In this embodiment, the two lock tongues are staggered with each other. Taking the direction shown in the figure as an example, one lock tongue is arranged at the left end of the other lock tongue. The side walls of the two lock tongues are in contact with each other, or there is a slight gap. The thickness of the two lock tongues is relatively thin. Therefore, there will not be a large lateral distance between the two lock tongue pushers, ensuring that the lock tongue switch slot can normally push the lock slot to open and close.

[0064] See also Figure 1-3 As shown, the door lock mounting frame 71 includes a bottom plate 711 and a lock tongue mounting plate 712 mounted on the bottom plate 711. The lock tongue mounting plates 712 are two pieces, and the bottoms of the two lock tongue mounting plates 712 are installed on the bottom plate 711 at intervals. Both ends of the lock pin 721 are installed on the two lock tongue mounting plates 712, and the top of the lock tongue mounting plate 712 is arranged below the bottom surface of the lock slot 7223.

[0065] The middle part of the bottom plate 711 is provided with a connecting slide groove 713 with two ends passing through, and the slide plate 73 is slidably arranged in the connecting slide groove 713;

[0066] The top of the bottom plate 711 is provided with a clearance groove (not shown) connected to the connecting slide groove 713 , and the bottom of the lock tongue pushing portion 7224 passes through the clearance groove and is arranged in the lock tongue switch groove 731 .

[0067] In this embodiment, the base plate is directly mounted and fixed on the ground, or fixed on the corresponding fixed object directly below the rolling door, and the slide plate slides directly in the connecting slide groove of the base plate, and the sliding limit of the slide plate is realized by the connecting slide groove. In this embodiment, taking the illustrated direction as an example, the two ends of the connecting slide groove are respectively connected to the left end face and the right end face of the base plate, and the middle part of the slide plate slides in the connecting slide groove, or the slide plate is completely in the connecting slide groove, and the lock tongue mounting plate is used to support and fix the lock pin. The setting of the clearance groove is used for the bottom of the lock tongue pushing part to pass through the clearance groove and insert into the lock tongue switch groove. Of course, as another embodiment, the connecting slide groove is set on the two lock tongue mounting plates, which are below the lock pin, and the slide plate slides in the connecting slide groove at the bottom of the two lock tongue mounting plates, and the slide plate is horizontally slid and limited by the lock tongue mounting plate and the connecting slide groove. At this time, there is no need to set the clearance groove on the base plate, which is convenient for the processing of the base plate and reduces the processing difficulty. It can be selected according to the actual situation.

[0068] See also Figure 1-3 As shown, a shell 714 is also installed on the bottom plate 711, and the shell 714 is a hollow structure with openings at the top and bottom, and the lock tongue 722 and the lock tongue mounting plate 712 are arranged in the shell 714; the left and right outer walls of the shell 714 are respectively provided with transverse clearance grooves 715 connected to the interior of the shell 714, and the transverse clearance grooves 715 are arranged opposite to the lock grooves 7223, and the top of the transverse clearance grooves 715 is connected to the top of the shell 714.

[0069] In this embodiment, the housing plays a protective role, preventing the lock tongue from directly leaking out, which is more beautiful. Furthermore, due to the existence of the housing, the lock accessory of the rolling door needs to enter the lock slot, so it is necessary to give way to the lock accessory. Therefore, by setting the transverse giving way slot, it is convenient for the lock accessory to move downward into the lock slot.

[0070] See also Figure 2 As shown, the transverse clearance groove 715 is a V-shaped structure with a larger upper portion and a smaller lower portion, and the bottom of the transverse clearance groove 715 is arranged below the bottom of the locking groove 7223 .

[0071] In this embodiment, the width of the transverse give way groove is greater than the width of the lock groove. Therefore, in the process of the lock accessory of the rolling door moving down into the lock groove, the transverse give way groove also adopts a V-shaped structure, and the bottom of the transverse give way groove is an arc-shaped surface, which also plays a role in guiding the downward movement of the lock accessory, so that the lock accessory can smoothly enter the lock groove, so that when the lock groove is closed, the lock accessory can be smoothly limited by the lock groove.

[0072] Of course, for the convenience of processing, the bottom plate directly adopts a U-shaped structure with an open top, and then a pad is installed on the bottom plate, the slide plate directly slides between the bottom plate and the pad, and the lock tongue mounting plate is installed on the pad, which can be selected according to the actual situation. Or the bottom plate is composed of two pads and two side plates, the two ends of the two side plates are respectively connected to the front and rear sides of the two pads, and the lock tongue mounting plate is installed on the upper pad.

[0073] See also Figure 4 , 5 As shown, a ball 7226 is rotatably mounted on the bottom outer surface of the lock tongue push portion 7224, and the ball 7226 is arranged in the lock tongue switch slot 731. When the lock slot is opened or closed, the outer surface of the ball 7226 abuts against the inner walls of the first end 732 and the second end 733 corresponding to the lock tongue switch slot 731.

[0074] In this embodiment, in order to ensure that the sliding plate is in the process of sliding, when the lock tongue switch slot drives the lock tongue pusher to smoothly rotate around the lock pin, the sliding contact and sliding friction are prevented from causing problems such as jamming, noise, and mode. Therefore, by arranging a ball on the outside, during the movement of the sliding plate, the lock tongue switch slot and the ball are in rolling contact, so as to ensure the smooth rotation of the lock tongue pusher around the lock pin, prevent the occurrence of rigid friction, mode, and jamming, and reduce the maintenance rate and extend the service life. Among them, due to the existence of the ball, the end of the first end and the second end is an arc surface, and the arc surface matches the outer surface of the ball, so as to ensure that the ball is in the corresponding first end and second end respectively when the lock slot is in the open and closed state and will not shake.

[0075] See also Figure 8 As shown, the utility model also provides a special rolling door lock for a silver pavilion, including two traction mechanisms 74, and also includes the above-mentioned door lock assembly 7, the two traction mechanisms 74 are respectively arranged on both sides of the door lock assembly 7, and a connecting rod 75 is respectively provided at both ends of the slide plate 73, and the two traction mechanisms 74 are respectively connected to the connecting rods 75 on both sides of the slide plate 73; the two traction mechanisms 74 respectively drive the slide plate 73 to move horizontally through the corresponding connecting rods 75 to open or close the lock groove 7223.

[0076] In this embodiment, the two traction mechanisms are components capable of driving the slide plate to move laterally along the door lock mounting frame (connecting slide groove), for example, the traction mechanism adopts one or more combinations of electromagnetic traction device, traction electromagnet, cylinder, electric cylinder or spring, preferably, the traction mechanism adopts electromagnetic traction device (or traction electromagnet). In this embodiment, both traction mechanisms adopt electromagnetic traction devices, which are connected through connecting ropes and corresponding connecting rods. This method can only make the traction mechanism occupy a small lateral space, will not occupy too much lateral space, and is also easy to arrange.

[0077] Of course, the two traction mechanisms include an electromagnetic traction device and a spring, and a spring is connected to a connecting rod. Taking the direction shown in the figure as an example, the spring is on the right side of the slide plate, and the electromagnetic traction device is on the left side of the slide plate. The spring always pulls the slide plate to move to the right, and the lock tongue pusher is in the second end, that is, the lock slot is in a closed state. When the rolling shutter door is closed, the deadweight of the rolling shutter door drives the lock attachment at the bottom to move downward, and it abuts against the inclined surface of the lock hook, and pushes the lock hook to rotate outward by its deadweight, that is, the bottom of the lock tongue pusher gradually rotates inward. At this time, the lock tongue pusher pushes the slide plate to move to the right in the opposite direction, and the spring is stretched by the connecting rod. After the lock attachment enters the lock slot, due to the existence of the spring restoring force, the restoring force of the spring pulls the slide plate to move to the right through the connecting rod, so that the lock slot is automatically closed. When it is necessary to unlock, the electromagnetic traction device on the left works, driving the slide plate to move to the left, thereby driving the lock slot to open, and realizing the unlocking function. When the unlocking is completed, the lock attachment moves upward and out of the lock slot, the electromagnetic retractor stops working directly, and the spring reset pulls the slide plate to move to the right, realizing the automatic closing of the lock slot.

[0078] Further, in order to increase the locking quality and effect of the rolling door and enhance its anti-theft and explosion-proof performance, the door lock assembly 7 is at least two groups, and the multiple groups of the door lock assembly 7 are arranged at intervals in the horizontal direction, and the slide plates 73 between the adjacent door lock assemblies 7 are connected via the connecting rod 75;

[0079] The two traction mechanisms 74 are respectively arranged on both sides of the door lock assembly 7 at the two ends, one traction mechanism 74 is connected to the connecting rod 75 at one end of the door lock assembly 7, and the other traction mechanism 74 is connected to the connecting rod 75 at the other end of the door lock assembly 7.

[0080] According to the actual situation required, since the widths of the rolling shutter doors of different silver kiosks are inconsistent, different numbers of door lock assemblies can be selected according to the widths of the rolling shutter doors of different silver kiosks. For example, two sets of door lock assemblies are selected, so that the right end of the slide of the door lock assembly on the left is connected to the left end of the slide of the door lock assembly on the right through a connecting rod, the right end of the slide of the door lock assembly on the right is connected to the traction mechanism on the right through a connecting rod, and the left end of the slide of the door lock assembly on the left is connected to the traction mechanism on the left through a connecting rod. If there are three sets of door lock assemblies, the two ends of the slide of the middle door lock assembly are respectively connected to the slides of the door lock assemblies on both sides through a connecting rod, so that the slides of the three sets of door lock assemblies form a whole. When the traction mechanism works, it can drive all the slides to move synchronously at the same time, so that all the lock tongues work together and the lock slots are opened or closed at the same time.

[0081] By using multiple sets of door lock components, their quantity and position can be adjusted according to the width of the rolling door, so that the locking limit is set for different rolling door positions, ensuring the locking stability and quality of the door lock on the rolling door.
